            Bug ID: 232995
           Summary: CSS hover does not trigger on click-command on iOS
           Product: WebKit
           Version: Safari 14
          Hardware: iPhone / iPad
                OS: iOS 14
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebDriver
          Assignee: webkit-unassigned at lists.webkit.org

When testing on iOS 13 and 14 in Safari using Appium, we launch a simple web page with some divs that have a hover effect. Clicking on the div should activate the hover effect on mobile devices. This happens when we exectue the click manually. But the command session/some_session_id/element/some_element_id/click does not trigger a hover effect. A simple html page for reproducing the behavior can be found below.

Issue was reported already 3 years ago: https://discuss.appium.io/t/invoke-hover-state-in-safari-ios/22853

Steps to reproduce the behavior:

<head>  
  <style>
    .test1 {
      display: flex;
      width: 200px;
      height: 50px;
      background-color: yellow;
    }

    .test2 {
      display: flex;
      width: 100px;
      height: 25px;
      background-color: red;
    }
    .test2:hover {
      background-color: green;
    }
    .test1:hover {
      background-color: blue;
      }

  </style>
</head>
<body>
  <div class="test1" onclick="void(0)">
    Test 1
    <div class="test2" id="test" onclick="void(0)">
      Test 2
    </div>
  </div>
</body>
